閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)。

　　In many developing countries, it is difficult to keep food cool. Most areas do not have electricity to operate the devices, called refrigerators, to keep food cold. Within days, food often spoils or becomes unsafe to eat. This can cause disease and loss of money for farmers. However, in Nigeria, one man is working to change this.

　　Mohammed Bah Abba, a teacher, invented a cooling device using two round containers made of clay. Mr. Abba's invention is called a Pot-in-Pot Preservation Cooling System. A small spot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables of drinks. A wet cloth coves the whole cooling system. The device keeps some foods fresh for several weeks.

　　Food stored in the small pot is kept from spoiling through a simple evaporation process (過(guò)程). Water in the sand between the two pots evaporates through the surface of the larger pot where drier outside air is moving. The evaporation process causes a drop in temperature of several degrees. This cools the inner container and helps destroy harmful bacteria found in food.

　　Mr. Abba started producing his cooling device in 1997．Since then, he has given more than 20,000 devices to people in villages in Nigeria. He expects that within five years, people all over the country will be using his invention. Mr. Abba also hopes to export his Pot-in-Pot cooling system to other hot, dry nations facing similar problems.

　　The Rolex Watch Company of Switzerland has also recognized the value of this cooling system. Two years ago, Mr. Abba received the Rolex Award (獎(jiǎng)賞) for Enterprise. This award is given every two years. It awards people trying to develop projects aimed at improving human knowledge and well-being. Winners receive financial assistance to help develop their projects.
